The purpose of this study was to determine whether an alert to get up once per hour while at work would reduce sitting time, increase sit-to-stand transitions, and improve perceived wellness in women with sedentary jobs.
Female university staff and administrators (48 ± 10 years) were randomly assigned to control-control (CC) (n = 22) or control-intervention (CI) (n = 22) groups. Both used a thigh-worn postural-based activity monitor for 2 weeks. The CC group maintained normal behaviors, whereas the CI group maintained behaviors during control week, but received hourly alerts on their computer during work hours in the intervention week. Time sitting and sit-to-stand transitions during an 8.5-hour workday were examined. A perceived wellness survey was completed at baseline and after the control and intervention weeks.
Among all participants (N = 44) during the control week, 68% of the workday was spent sitting and 41 sit-to-stand transitions occurred. An analysis of variance revealed no statistically significant differences in variables over time (P > .05). There was a significant increase in perceived wellness from baseline in both groups (P ≤ .05). Perceived wellness showed no statistically significant difference between groups.
The intervention had no statistically significant effect on sitting time or sit-to-stand transitions. Participation improved perceived wellness in the absence of behavior change.
